Anyone familiar with Respironics 'SleepLink'

I have just obtained another Resp machine (from a US clinic that trialled it (only 5 hrs on the clock)) and it has arrived with some bits that I haven't seen before.

The datacard is not the normal memory card but is a SleepLink module - it looks like a datacrad but with a plastic housing attached at the end that sticks out of the datacard slot - this plastic block has a socket for a cable - the cable plug looks most like a video S-connector cable but has 8 pin holes in three rows - 2 then 3 then 3. Possibly part # 1007492.

There is also an adapter part #1006102 that looks like a serial null-modem adapter.

A small card I have indicates that there is a cable that goes from the SleepLink & connects to the null-modem adapter & that then connects to a DB9-RJ45 cable (part 1023456)

Another pic shows a device between the sleeplink and the PC called an Analog Output Module (AOM) System (part 1006966


My basic question is, can this be hooked up to a PC running Respironics Encore Pro & gather the data. (if not, I can just stick to the std datacard & card reader).

Am wondering how useful this SleepLink module is seeing it was provided with the machine.

dsm -

ResMed has a product called "ApneaLink"

http://www.resmed.com/en-us/products/cl ... u=products

which might or might not perform similar functions. This has its own software. You might get some hints by comparing the two. A .pdf of their clinical guide is available.

Velbor,

Thanks for the link - I have seen the ApneaLink before as it is a screening device. Take it home wear it for a night & it will give an assessment (some doubt the accuracy) as to one's OSA apnea rating.

I did find some PDFs that mention Respironics SleepLink & it seems to be a family of devices and one reference mentions there being an oximetry module but I can't substantiate that.

From a closer look at the diag in a card that came with the bits I now have it appears to be a way of passing the sleep data directly to a PC set up in a control room nearby so it seems to be a clinical device not intended for the public. It plugs into the datacard slot. My guess is that it converts the data being written to a datacard into serial data that can either be sent by a special modem (the AOM module) or by direct cable.

SleepLink seems to be in two versions so has been around a while (SleepLink & SleepLink II).

Cheers

sleeplink is also used in testing and to calibrate a respironics machine at a repair site

Also,

Re my ref to oximetery - Wulfman sent me info that shows that Respironics machines also use the same xPOD (or iPOD) Nonin oximeter unit for gathering SpO2 data that is used as part of the Resmed Reslink unit.

I plan to get one of the iPOD units (I actually have some already but they are no the correct data format for the Resmed Reslink nor I suspect the Respironics Oximetry SleepLink.

So a new question I have is what Respironics software can read oximetry data and display it ?

Thanks to Den I extracted this pic of the bit I have - except mine doesn't have the cable (that clearly got left out).

Next step will be to get the missing cable ! - but from where ?

That looks like the interface the sleep lab would use to interface into their computer system for titrations, the Respironics people also have one to demonstrate the machine, they like to hook it up to a laptop and show you how magical it is (sorta like turning on the monitor mode in Silverlining).

I would hang on to it, somebody goofed that you have it. It is just a serial communications cable, we have talked about before to get around Respironics no EncorePro for the patient issue.

You can tap into the serial communications port of the machine via that SmartCard interface and sniff similar to network sniffing.

Probably only 3 wires in actual use on that cable, tx, rx, and signal ground. Got a scope? take that sucker apart and see what wires are used, I'm sure it traces down to the SIM chip normally found on the card, you can do the same thing with the SmartCard if you know what you are doing, do it wrong and you 99 the SmartCard, but with that interface you bypass that problem.

Snoredog,

Recent I obtained some Nonin xPod units (oximeter only) and some Nonin iPod units (oximeter built into a probe) - the ones I got though are more sophisticated than the one Resmed uses & it seems Respironics use to gather oximetry data.

The xPod is an Spo2 unit in a connector & the iPod is a complete SpO2 and probe built into the probe (just like a smaller finger SpO2 unit).

This link shows both the iPod and the Xpod and explains the diffs plus it shows the OEM III oximetry unit.

These units come out with 2 types of data output mode #1 & mode #2 - the #1 (used as part of Resmed's Reslink & as mentioned, I believe also is the same mode used in Respironics SleepLink family) outputs 3 bytes of data per sec & the mode #2 unit outputs 5 bytes - 75 times per sec (real time).

The ones I ended up with are the mode #2 which output too much data for the Resmed & Resp data gathering. The price to buy an xPOD and an 8000AA probe for the Resmed & Resp units is around $US1200. Am hoping to find a way to do them a lot cheaper.

I paid a fraction of that for the units I got - just a pity they are the more sophisticated versions.

#2 This link also shows the units on a Nonin web page ...

Here is a pic showing the Respironics SleepLink modem unit & notice it also shows a Nonin xPOD (with a Nonin flexiwrap SpO2 probe) as the oximetry unit.

This xPod is the same identical oximetry unit used with Resmed Reslink.

Thanks to Den (Wulfman) for this info. In time I will put all this xPod & iPod data up on my website.
